Not much of one. It has the factory 73 340 rear springs with (uh....) airshocks on the rear, and a 1.00" torsion bar up front with KBY shocks. So it really has no setup at all. I let out some air from the shocks to lower the rear, and lowered the tires to ~18 psi.
I read your post on the other thread about suspension setups. I want the car to handle nicely in the surces, hence the bigger torsion bars, and will likely go with a a bigger front sway and add a rear sway bar. But what would you suggest for better grip at the track? Incidentally, the airshocks allow me to raise the rear about 2" to keep the rear tires rom hitting the front fender lip on a bump or pothole. Maybe compensating for old springs?
